NVIDIA GTX 560 Issues

Hi guys,
I'm hearing people are having loads of issues with these cards..

NVIDIA Forum Thread

I'm not sure what to make of this, as I have had no issues.
Well I say no issues, I did have a weird TDR after I connected my WD My Book to an eSATA on the JMicron controller, disabled that controller and put the My Book back on USB and haven't had an issue.
I don't consider this as a GFX issue as this My Book has caused BSODs on eSATA before on my old ASUS P5Q Deluxe Marvell controller.

I'm interested to hear what you guys make of this. Are you running a GTX 560 without issue?
